This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.4,"severity":"medium","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},{"score":6.4,"severity":"medium","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793787446793,"publishedAt":1793784366627,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/056a6984-4753-4f52-87b0-1a3cc2f5bde2?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.43.1/inc/integrations/forms/gravity-forms.php#L22"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.43.1/inc/integrations/forms/gravity-forms.php#L13"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.41.0/inc/integrations/forms/gravity-forms.php#L22"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.41.0/inc/integrations/forms/gravity-forms.php#L13"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3776057/simple-cloudflare-turnstile/trunk/inc/integrations/forms/gravity-forms.php"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.41.0/inc/integrations/forms/gravity-forms.php#L13"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.41.0/inc/integrations/forms/gravity-forms.php#L22"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.43.1/inc/integrations/forms/gravity-forms.php#L13"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/simple-cloudflare-turnstile/tags/1.43.1/inc/integrations/forms/gravity-forms.php#L22"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3776057/simple-cloudflare-turnstile/trunk/inc/integrations/forms/gravity-forms.php"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/056a6984-4753-4f52-87b0-1a3cc2f5bde2?source=cve"}],"remediation":[],"revision":"d2e1f6466f4482aef9c62156f851cb70c81f72846b551e9678678f064f06c559","sources":[{"modifiedAt":1793784366627,"name":"CNA: Wordfence","retrievedAt":1793786937332,"url":"https://www.cve.org/CVERecord?id=CVE-2026-93900"},{"modifiedAt":1793787446793,"name":"NVD","retrievedAt":1793794572821,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93900"}],"ssvc":null,"status":"published","title":"Simple CAPTCHA with Cloudflare Turnstile <= 1.44.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","updatedAt":1793794572821}
